I am about to purchase a DC lv 4 12in sub with d2 coils with a Audioque 1200w @ 1 ohm amp. I was wondering if my car, which is a 2010 Scion xD, can handle a 1200w amp just the way it is or do i need to install a capacitor or do the big 3 installation. Please post if it can or cant handle the amp and if it cant handle it what should i do to make it work, thanks in advance.
